Butterfly Sample Case- AssertionError

Hi everyone- I am new to Butterfly. I’ve tried to run some of the scripts from Hydra but haven’t been successful. So I’m hoping when this error from the Sample Case script is resolved, it might solve other problems…

I’m getting an assertion error on the component Butterfly_SampleCase. See screenshot below and the error from OpenFOAM is pasted underneath.

More info:

  • I am running Rhino 6 in Administrator mode.
  • I’m running Butterfly ver 0.0.05. I’ve updated all of the components on the Hydra script (from ver 0.0.04)
  • I have Blue CFD installed (Core-2017)
  • All plugins were added to my computer May 2020

Let me know if I need to provide more info.

Thanks!
Sue

Did you find a solution? I have the exact same issue

I did not. I ended up following Lecture 8 of this series https://vimeo.com/showcase/7101158 to visualize Butterfly results in Paraview.
